To all whom imwy concern:

Be it known that I, JOHN N. FrsK, a citizen of the Dominion of Canada, residing in the parish of St. James, in the county of Char,- lotte and Province of N ew Brunswick, Canada, have invented certain new and useful Improvements in Combined Derricks and Carriers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a device for raising, supporting, and carrying heavy articlesas rock-and may for purposes of this description be called a combined derrick'and carrier. The novelty consists in the con-` struction, arrangement, and adaptation of parts, as will be more fully hereinafter set forth, and specifically pointed out in the claims. Upon the forward bolster or head block and from near the rear axle I support strong frames, which, being secured together at the tops, form a strong and reliable derrickframe. Stout side bars serve to maintainthe relative positions of these parts, andthey are placed sufficiently distant from each other4 to allow the article being operated upon to be drawn up between them. The derrick is.` mounted on stout but ordinary running-gear,

a block and tackle. The rope or chain ofthe tackle is wound upon a drum journaled in the carrying a pinion which meshes with a multiplying gear upon the drum furnishes means for revolving the drum and elevating the load. These gears may be thrown out of mesh when it is desired to lower the load, and a leverbrake allows the load to be lowered at will.

The invention is illustrated in the accompanying drawings,in which Figure l is aside elevation of the device; Fig. 2, a rear view, and Fig. 3 a plan.

Referring to the drawings,A designates the ordinary running-gear of a stout wagon, .eX- cept that it has the side bars, a, arranged so far apart as to admit the rock or load being passed upward between them, and that a plat. form, A', is provided upon either side to allow standing place for the crank-operators. The derrick-frame B is composed of the inclined standard-frames B and B2, the former being supported at its bottom over the rear Patented in Canada June 5, 1834, No. 30,777.

axle and the latter upon the 'forward headdepends a` hook, b', which supports the upper i.

block, c, of the tackle G. In an extension B3 to the standards B is,journaled the drumshaft D', and thisis so arranged that the drum D lies directly over or nearly over the load, so as to give an approximatelydirect strain to the tackle. At one end the drum-shaft D carries a rigid gear, E, which in operation meshes with a pinion, f, upon a shaft, F, which shaft carries upon either end a crank. f', arrangedvdirectly over the standingplaces or platforms A. The standard-frame B2 is braced bycross-braces g2, but in order tomakc room for the convenient use ofthe gearing I provide the standards B' with onelong brace, g', and run a short brace, g3, from the base up to the brace g', as shown. The shaft Fhas longitudinal movement in its bearings, but is held with its pinion in mesh by a latch, H, which is pivoted at one end to the frame B3 and operates between the collars I onthe shaft F. When it is desired to throw the pinion out of mesh with Vthe gear-wheel E of the drum, it is onlyv necessary to lift the latch out of contact with the collars I and move the shaft F endwise. The gear E may be provided with a friction-surface, or the lever M, pivoted at m to the crossibar b, may be caused to have frietional'contact with the wheelteeth; or the shaft F may, at the gearend thereof, be hung in movable bearings, which will allow the pinion f to be thrown out of mesh when the lever-brake is in operation. In either case this brake is applied to the drum for the purpose of holding the drum until the gearing is thrown out of mesh and then lowering the load at will. is arranged transverse to the plane of the machine to bring the cranks over the platforms, so that two men may work simultaneously.

The machine is adapted t-obe worked by two men, one of which is the driver, and the side bars, a, afford convenient footing by which said driver may pass from his seat to the platform A and return.

What I claim as new is-d 1. The combination, with the running-gear A, having side bars, a, and platform A', as

The shaft F rco described, the derrick-frame, the block and tackle, and the operating-cranks arranged on a transverse shaft, as set forth.
